【中文标题】将 VHD 从 azure 磁盘复制到 azure 存储帐户

【英文标题】：Copy VHD from azure disk to azure storage account

【问题描述】：

我有一个 Windows 10 系统的 Azure 磁盘。我希望此磁盘必须转换为 VHD，并且应该在 azure 存储帐户中可用。

简单地说，我希望我的 Azure VM 数据磁盘存在于 azure 存储 BLOB 中，而无需将 VHD 下载到我的基础计算机上。可能吗。如果是，请指导我。

谁能帮帮我。

谢谢

【参考方案1】：

是的，这是可能的。您可以将托管磁盘复制到 VHD 文件中并将其存储在存储中。下面是通过 PowerShell 的示例代码：

#Provide the subscription Id of the subscription where managed disk is created
$subscriptionId = "yourSubscriptionId"

#Provide the name of your resource group where managed is created
$resourceGroupName ="yourResourceGroupName"

#Provide the managed disk name 
$diskName = "yourDiskName"

#Provide Shared Access Signature (SAS) expiry duration in seconds e.g. 3600.
#Know more about SAS here: https://docs.microsoft.com/en-us/Az.Storage/storage-dotnet-shared-access-signature-part-1
$sasExpiryDuration = "3600"

#Provide storage account name where you want to copy the underlying VHD of the managed disk. 
$storageAccountName = "yourstorageaccountName"

#Name of the storage container where the downloaded VHD will be stored
$storageContainerName = "yourstoragecontainername"

#Provide the key of the storage account where you want to copy the VHD of the managed disk. 
$storageAccountKey = 'yourStorageAccountKey'

#Provide the name of the destination VHD file to which the VHD of the managed disk will be copied.
$destinationVHDFileName = "yourvhdfilename"

#Set the value to 1 to use AzCopy tool to download the data. This is the recommended option for faster copy.
#Download AzCopy v10 from the link here: https://docs.microsoft.com/en-us/azure/storage/common/storage-use-azcopy-v10
#Ensure that AzCopy is downloaded in the same folder as this file
#If you set the value to 0 then Start-AzStorageBlobCopy will be used. Azure storage will asynchronously copy the data. 
$useAzCopy = 1 

# Set the context to the subscription Id where managed disk is created
Select-AzSubscription -SubscriptionId $SubscriptionId

#Generate the SAS for the managed disk 
$sas = Grant-AzDiskAccess -ResourceGroupName $ResourceGroupName -DiskName $diskName -DurationInSecond $sasExpiryDuration -Access Read 

#Create the context of the storage account where the underlying VHD of the managed disk will be copied
$destinationContext = New-AzStorageContext -StorageAccountName $storageAccountName -StorageAccountKey $storageAccountKey

#Copy the VHD of the managed disk to the storage account
if($useAzCopy -eq 1)

    $containerSASURI = New-AzStorageContainerSASToken -Context $destinationContext -ExpiryTime(get-date).AddSeconds($sasExpiryDuration) -FullUri -Name $storageContainerName -Permission rw
    $containername,$sastokenkey = $containerSASURI -split "\?"
    $containerSASURI = "$containername/$destinationVHDFileName`?$sastokenkey"
    azcopy copy $sas.AccessSAS $containerSASURI

else

    Start-AzStorageBlobCopy -AbsoluteUri $sas.AccessSAS -DestContainer $storageContainerName -DestContext $destinationContext -DestBlob $destinationVHDFileName

但在我的测试中，当你使用azcopy 命令时，VHD 文件有问题。命令Start-AzStorageBlobCopy 运行良好。所以我为你推荐命令Start-AzStorageBlobCopy。更多详情请见Export/Copy the VHD of a managed disk to a storage account in different region with PowerShell。

非常感谢。我会乖乖地试试这个。希望它有效。再次提前感谢。如果我被卡住了，我会回来的。
